This offers 32 hosts per subnet, but yet again the first and last host per subnet are reserved and cannot be used. This offers 30 usable hosts per subnet, which is adequate for the number of hosts on the network.)
Default Gateway: 199.100.50.33. (I am going to use subnet #1. the default gateway for this subnet will be the first usable network address in the subnet, hence 199.100.50.33.)
Number of Subnet Bits: 3 (2^3 = 8 – 2 = 6).
Number of Host Bits: 5 (2^5 = 32 – 2 =30).

Fig 1 shows the relationship of subnet bits (S) to host (H) bits in the octet.
